Allyl iodide
Allyl iodide (3-iodopropene) is an organic halide used in synthesis of other organic compounds such as N-alkyl-2-pyrrolidones, sorbic acid esters, 5,5-disubstituted barbituric acids, and organometallic catalysts. Allyl iodide can be synthesized from allyl alcohol and methyl iodide on triphenyl phosphite, Finkelstein reaction on allyl halides, or by the action of elemental phosphorus and iodine on glycerol. Allyl iodide dissolved in hexane can be stored for up to three months in a dark freezer at −5 °C (23 °F) before decomposition into free iodine becomes apparent Wikipedia

The maximum degree of filling must not exceed the degree of filling determined by the following:<br>  <br>Where: <br>t<sub>r</sub> is the maximum mean bulk temperature during transport, <br>t<sub>f</sub> is the temperature in degrees celsius of the liquid during filling, and <br>α is the mean coefficient of cubical expansion of the liquid between the mean temperature of the liquid during filling (t<sub>f</sub>) and the maximum mean bulk temperature during transportation (t<sub>r</sub>) both in degrees celsius. <br>b. For liquids transported under ambient conditions α may be calculated using the formula:<br>  <br>Where: <br>d<sub>15</sub> and d<sub>50</sub> are the densities (in units of mass per unit volume) of the liquid at 15 °C (59 °F) and 50 °C (122 °F), respectively.
